Printer Selection table permissions for regular user

Hello,

I have a codeunit which modifies the printer selection for a report. Before you print the report, it is changed to our own printer and after, the printer is restored to the original printer. This works for a super user, but not for a regular user. I have added rights for the printer selection table and table data for the regular user, however when I run the report, NAV crashes sometimes when I'm setting the printer selection and sometimes when I'm restoring the printer selection.

Does anyone know why this would happen for a regular user but not a super user? Are there any other permissions needed aside from the printer selection table and table data which has already been added?

Here is a snippet from the codeunit which runs the report:

SetPrinterSelection;
REPORT.RUNMODAL(TheReportID, FALSE, FALSE, Records);
RestorePrinterSelection;

Here is the definition for SetPrinterSelection:

SetPrinterSelection()

// delete any records in the temp printer selections record
TempPrinterSelections.RESET;
TempPrinterSelections.DELETEALL(FALSE);

// filter the printer selections by report id and user id
PrinterSelections.RESET;
PrinterSelections.SETRANGE(PrinterSelections."Report ID", TheReportID);
PrinterSelections.SETRANGE(PrinterSelections."User ID", USERID);

// if a record exists for this user and report we need to save it off and modify it
// there cannot be more than one record with these filters
IF PrinterSelections.FIND('-') THEN
BEGIN
    // save the printer selection into the temporary table
  TempPrinterSelections := PrinterSelections;
  TempPrinterSelections.INSERT;

  // change the printer selections record so it will now print to the api printer
  PrinterSelections."Printer Name" := 'Zetadocs Automation Subsystem';
  PrinterSelections.MODIFY;
END
ELSE
BEGIN
  // if there are no records we need to make a new one for this user and report
  PrinterSelections.INIT;
  PrinterSelections."Report ID" := TheReportID;
  PrinterSelections."User ID" := USERID;
  PrinterSelections."Printer Name" := 'Zetadocs Automation Subsystem';
  PrinterSelections.INSERT;
END;

// make sure the transaction is committed to the database
COMMIT;

Here is the definition for Restore Printer Selection:

RestorePrinterSelection()

// filter the printer selections table so we will see the selections for this report
PrinterSelections.RESET;
PrinterSelections.SETRANGE(PrinterSelections."Report ID", TheReportID);
PrinterSelections.SETRANGE(PrinterSelections."User ID", USERID);

// We should always find one record because we put it there
IF PrinterSelections.FIND('-') THEN
BEGIN
  TempPrinterSelections.RESET;
  IF TempPrinterSelections.FIND('-') THEN
  BEGIN
    PrinterSelections := TempPrinterSelections;
    PrinterSelections.MODIFY;
  END
  ELSE
  BEGIN
    PrinterSelections.DELETE;
  END;
END;

COMMIT;

Any help would be greatly appreciated.
